Orders are created asynchronously: a valid request returns immediately with a 202, and an order.created webhook is sent when processing completes. If creation fails terminally, an order.create_failed webhook is sent instead. Identify the test or procedure to order with either item_id or name. Discover valid values via Search Order Catalog. When both are provided, item_id wins.

Request Parameters

Required Fields

type (string, required): Order type. One of lab, imaging, or procedure.
patient_mrn (string, required): Medical Record Number of the patient the order is for.

One of the following is also required:

item_id (string): EMR catalog id of the test/procedure to order. Discover ids via POST /v1/orders/catalog/fetch.
name (string): Catalog name of the test/procedure, resolved against the catalog when item_id is omitted.

Optional Fields

provider_id (string, optional): EMR id of the ordering provider.
facility_id (string, optional): EMR id of the ordering facility/location.
assigned_to_id (string, optional): EMR staff id the order is assigned to.
order_date (string, optional): Order date (ISO 8601, YYYY-MM-DD).
collected_date (string, optional): Specimen collection date (ISO 8601, YYYY-MM-DD). Labs.
collection_time (string, optional): Specimen collection time, e.g. "12:58 PM".
performed_date (string, optional): Performed date (ISO 8601, YYYY-MM-DD). Diagnostic imaging.
high_priority (boolean, optional): Flag the order high priority.
notes (string, optional): Order notes.
clinical_info (string, optional): Clinical information for the order.
callback_urls (string[], optional): URLs to receive the order.created webhook, in addition to the account webhook.
